Potomac Horse Fever - contd.
Clinical signs of PHF are similar to those of salmonellosis in equines. Horses often will develop a fever a few days after infection that passes and may not be detected. Approximately two weeks after infection, the horse will again develop a fever that may be accompanied by clinical signs of colic; diarrhea that can be mild to severe; depression; and anorexia, or an absent appetite. Other symptoms include leukopenia, or a low white blood cell count; congested mucous membranes; hypercoagulability, or conjoining of platelets in the blood stream; and laminitis.
